It’s powered by a new processor, what Kipman called a holographic processing unit. It’s equipped with sensors to detect the real world and gestures of the user, as well as holographic sound. It has no wires and doesn’t need to connect to phones or PCs. Holographic APIs are built into all Windows 10 devices, and Kipman invited developers of Magic Leap, Glass, and Oculus to come work with it. He said it would be "available in the Windows 10 timeframe."
